Application led November 8, 1911. Serial No. 659,092.

To all whom t may concern Be it known that I, NEWMAN H. HOLLAND, a subject of the King of Great Britain, and a resident of West Orange, in the county of Essex and State of Newv Jersey, have invented certain new and useful Improvements in Phonographic Apparatus, of which the following is a description.

My invention relates to phonographic apparatus and more particularly to a. combined telephone and phonograph, whereby oral communications over a telephone' line may be auttmatically recorded. p

The principal object of my invention is to provide 'a device of this character' having means for preventing the flow of current through the telephone circuit and thereby' preventing waste of current in said circuit when the phonograph is not in operation.

Tn its preferred form, my invention comprises a single operating member for simultaneously closing a gap in the telephone circuit and starting the phonograph motor, and means for maintaining said circuit open until the recorder is placed in operative position relatively to the record supporting mandrel, and until the clutch between the motor and record support is thrown in to cause the rotation of the mandrel. With this construction, the telephone circuit is not closed until the phonograph is completely adjusted for operation.

Other objects of my invention are the provision of improved details of construction and combinations as hereinafter more fully set forth and claimed.

In order that my invention may be more fully understood, attention is hereby directed to the accompanying drawings forming part of this specification and in which--A Figure 1is a diagrammatic view illustrating the preferred embodiment of my invention, some of the parts being shown in eleration; Fig. 2 is a central vertical sectionalv view of the preferred form of recorder used with my invention, a part of the circuit including said recorder being shown diagrammatic-ally; and Fig. 3 is a bottom plan view of the recorder.

lnall of the views. like parts are designated by the same reference numerals.

Referring to the drawings, the numeral 1 designates a circuit including a battery 2. a telephone transmitter 3, and a recording sound box 4 adapted to be placed in contact `with the surface of a record tablet (not shown) upon a horizontal record supporty ing mandrel 5. The mandrel 5 is mounted in the frame of the phonograph and is adapted to b e rotated b v a pulley7 7 supported 1n ahnement therewith on the frame of the phonograph and connected asby a belt Ylongitudinal movement thereon, this clutch being formed with a serrated lateral surface adapted to mesh with a correspondingly shaped surface adjacent the same on the pulley 7. The clutch 10 is adapted to be moved along the shaft 5 into or .out of engagement with the pulley 7 as by an arm`11 engaging within the groove 12 formed inf the periphery of the clutch, the arm 11 being provided with a downwardly projecting shank 13 rotatably mounted in the base plate of the phonograph slightly in front of the portion of the said arm in engagement with the clutch.

The numeral 14 representsa cross shaped member pivoted at the intersection of the two arms thereof, as at 15, to a lug 16 depending from the base plate of the phonograph. rThe upper arm of member 14 is pivotallv connected to one end of the link 17; which is pivotallv connected at its opposite end to a crank 18 secured to the. bottom of the shank 13 of the arm 11. Push buttons 19 projecting above the base plate ofthe phonograph and pivotallv connected at their lower ends to the lateral arms of the member 14- serve to oscillate thesaid member to shift the link 17 and therebv rotate the crank 1S and arm 11 to actuate the clutch 10. Pneumatic means mav also be emploved to operate the clutch l0. these means` as shown, comprising a cvlinder Q0, the interior of which is adapted to be connected. as bv the hollow angular connection Q1. with a rubber tube (not shown) connected to anv suitable device (not shown) for controlling the flow of air into and out of the cylinder 20. A.

suitable controlling device of this character has been invented by Charles Schiiil and is shown and described by him in an application Serial No. 572,796, filed July 20, 1910. A piston 22 is slidably mounted within the cylinder 20 and has pivotally connected thereto one end of a link or bar 23, the other end of which is pivotally connected to Ithe lower arm of the member 14. rl`he lower arm of the member 14 for a reason which will hereinafter appear is made of such a length that the link or `bar 23 is inclined at an angle to the axis of the cylinder 20. F low of air into and out of the cylinder causes the shift ing of the piston in the cylinder to rockthe member 14 on its pivot and operate the clutch 10 in the manner hereinbefore described. A

The recording sound box 4 is mounted in a spectacle frame 24 pivoted at 25 to the carrier arm of the phonograph for movement about an axis at an angle to the horizontal, the numeral 26 representing the guide rod upon which the forward end of the said arm is slidably mounted. The spectacle frame also carries a reproducing sound box 27 which is provided with a neck 28 adapted to be connected in a well known manner to an amplifying horn or other sound conduit (not shown). By movement of the spectacle frame 24 about the pivot 25, either the recording sound boxY 4 or the reproducing sound box 2T may be. moved at will directly into or out .of operative position with respect to a record cylinder on the mandrel 5.

The recorder which' l prefer to use in connection with my invention comprises a casing 30 provided with an electromagnet 31 connected in the circuit 1I` and with a diaphragm 32 located adjacent to the poles of the magnet 31. The bottom of the casing 30 is spaced from the diaphragm 32 and is provided with a central opening 33 of a smaller diameterthan the diaphragm 32. A ring ofrubber or other elastic material is secured to the outside ot' the casing concentric with the opening 33 and'supports a. diaphragm 35 ot' smaller diameter than the diaphragm 82. the diaphragm being provided with a stylus 36 for recording upon the cylinder 3T. When electric undulations or impulses are impressed upon the line or circuit 1 by Vthe transmitter 3, the diaphragm 32 is set into vibration by the magnet 31, the -air below the diaphragm 32 setting up in the diaphragm 35 and the stylus 36 corresponding vibrations, which are recorded by the stylus 3G in the cylinder 87. By employing the reduced sound passage 33 and a recording diaphragm smaller than the receiver diaplnagin-. the vibrations ot the diaphragm 32 are imparted with increased'amplitudeeto the stylus, and the record impression is correspomlinglv increased in depth, so that' a louder reproduction is obtainable. The sound box is preferably connected to the spectacle frame by a hinge Sil and is supported to permit a proper depth of cut of the stylus 'by a spring pressed arm 302 having a curved projection 36 engaging the record to one side of the stylus. This manner of supporting the sound box on the record is claimed and fully disclosed in my application, Serial No. 598,069, filed December 19, 1910.

In order to prevent the closing of the telephone circuit before the `motor is set into operation, I provide the lnotor circuit with spaced contacts 38 and 39 mounted upon one tace of a piece of insulation 40. the telephone circuit being provided with spaced.

contacts 41 and 42, likewise secured to the member 40 and having free ends extending into proximity to each other. The rear face of the contact 42 is provided with a backing 43 of suitable insulating material.

The numeral 44 represents a switch of conducting material provided with an insulating handle 45 and pivoted at 46 to the member 40. The switch 44 is provided with a laterally projecting toe 47 adapted to engage the insulation 43 when the handle 45 is shifted to the left. as shwn in Fig. 1` to force the contact 42 into engagement with the contact 41. this same adjustment of the handle serving to move the switch 44 into enga-gement with the contacts 38 and 39 and thereby close both the motor circuit and the gap between the contacts 41 and 42 inthe telephone circuit.

in order to prevent the closing ot' the telephone circuit-before the clutch is thrown into engagement with the pulley 7 to rotate the mandrel. l provide'the telephone circuit with two additional contacts 48 and 49 insulated 'from each otherv and preferably secured to the bottom ofthe cylinder 20. The contact 49 is so located as to face the contact 48 and is provided with a knife edge 49. The contact 48 is constructed of resilient material and tends normallr to cngage the knife edge 49. The forward end of the contact 48 is provided with an un wardly projecting extension 50 resting in engagement with the lower surface ot vthe inclined link or bar 28.y .its shown in Fig. 1. the piston is in the position corresponding to the disengagement olE the clutch 10 with the nullev 7. the Contact 48 being pressed hv the link or bar 28 out of engagement with the, kni'le edge 49 of the contact 49. nWhen air is forced into the cvlinder 20 to shift-the piston 22 from the position shown. the. extension 50 rides upwardly on the link lor bar Q3 and finally engages within the 'notch 23 .in the lower 'face ofsaid link or bar to `permit the Contact 48 to engage the kni'tc edge 49 and therebiv close. the, gap formed in the telephone-circuit by the prior separation of the said contacts. "When the morsen piston is again drawn back to the position shown in F ig. 1, the link 23 forces the projection 50 downwardly by wedging action and thereby moves the contact L18 out of engagement with the knife edge 49 of the contact 49.'

I also provide means for forming ay gap in the telephone circuit when the recorder is not in operative position. These means comprise a plurality of contacts 51y and 52 insulated from each other, 'the contact 52 being formed of resilient'material and having a tendency to contact the knife edge 51 on the contact 51. The contact 52 is adapted to be engaged by a finger or projection 53 on the spectacle frame 24 when the recorder is shifted out of operative position to thereby separate the contacts 52 and 51. By the means hereinbefore described, it is evident that the telephone circuit cannot be closed until the phonograph is completely adjusted for operation.
